mismatch between heat flux value
 

Hi friends

I have defined simple cylinderical geometry.

I have given heat flux value conditions for both the faces.

& circumferential face is being insulated.

I am getting less value on side where heat enters the geometry than where it leaves the geometry.

3619.92 against 4000

(The area of both the faces is same)

I have done steady state as well as unsteady state analysis.

Please tell me why it is happening.
